SF0868BA03209S
SAW Filter
868 MHz SAW Filter, 600 kHz 1 dB Bandwidth
• 3.0 x 3.0 mm LCC, 6 Pads
• RoHS Compliant
These filters are manufactured on quartz, which provides optimal temperature performance and are available from 80
-1600 MHz. This TCRF is designed for narrowband IF filtering such as in satellite transponders, directional finders and
anti-jam modems. Other packaging styles are available for more rugged environments and applications. Standard part
numbers as well as custom solutions are available. Please contact sales for more information.
